T0 a/ZZ whom, t muy concern:

Be it known that I, HIRAM BARBER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Heating- Stove, of which the followingis aspecification.

My invention relates to improvements in heating-stoves in which acombined cross-partition, register, and fuel-magazine are located abovethe grate, the object being to procure combustion of gases arising fromthe grate below. An air-shaft is also provided to afford asafety-ductthrough the cross-partition to prevent the escape of coal-gasinto the room. I attain these objects by the mechanism illustrated inthe accompanying drawings, in whichy Figure 1 is a sectional view of mydevice, showing the interior arrangement of the crosspartition andfuel-magazine and the register composed of the plates P and R, theairshaft A, and grate G. Fig. 2 is a plan View of the register composedof plates P and R when open-that is, the openings 0 and o coincidingandshowing also the Lipper end of the air-shaft A. Fig. 3 is a plan View ofthe register when closed.

In the construction of my heating device it will be observed that I makeuse of the plates P and R, which in combination form a crosspartitionand register located above grate G. The distance between the grate G andthe cross-partition is sufficient to aord a suitable chamber for thecombustion of fuel. The partition-plate P is provided with the openings0', which are preferably arranged in a Semicircular form. Superincumbentupon the partition-plate P is placed the register-plate R, which is alsoprovided with the openings 0, arranged in semicircular form tocorrespond with the openings o in the partition-plate P. Theregister-plate R is also provided with the handle h, which operates inthe slot S, provided in the casing K, and which slot is so arranged asto permit rotary motion of the reg ister-plate R and isof a suflicientWidth to permit the opening or closing of the openings o in thepartition-plate P by the register-plate R. The partition-plate P islocated a sufficient distance from the top of the stove to afford asecondary combustion-chamber above the partition-plate P for thecomplete combustion of the gases arising from the fire below thecross-partition when the degree of heat is sufficient to ignite the samein their passage through the openings o and o.

A is an air-shaft which is tightly inserted into the opening providedtherefor in the partition-plate P. The air-shaft A when in positionextends downward from the cross-partition, preferably near the outercasing K, toward the grate G a distance sufficient to secure an obliqueor side draft from the fire on the grate G through the air-shaft A whenthe openings o in the partition-plate P are closed by the superincumbentregister-plate R. The door d is provided for the. introduction of fuelwhen desired. As is usual in stoves of this general type, the door d maybe opened more or less, as desired, for the regulation of the fire inthe combustion-chamber between the 'cross-partition and the grate G. Thedoor CZ is provided for the removal of the debris arising from thecombustion of fuel upon the grate G.

The partition-plate P is provided with an opening, into which isinserted the fuel-magazine M, which is adapted to the size of the stoveand to the height of the coal-combustion chamber. The fuel is fed intothe magazine through the door d2. The magazine extends downward from thecross-partition and is closed at the top by the portable cover g, so asto prevent ordinary draft upward through the magazine, and thus tosecure the diversion of it either tothe register or to the safety-duct.When the utmost upward draft is desired, the cover may be removed.

X is the exit-Hue leading to the chimney.

When fuel is ignited upon the grate G and the openings o and o arecoincident, the gases arising from combustion ascend through the passageformed by the openings 0' and o and thence out through the pipe X. When,however, the apertures 0' in the partitionplate P are closed by theregister-plate R, the only exit for the gases arising from thecombustion of fuel upon the grate G is the air-shaft A. The air-shaft Ais never closed, and there is always to some extent a lloW of heatedgases upward through the same. The line of draft to the same from theignited fuel located upon the grate G is, however, oblique and not asforceful as the direct as- IOC cending draft through the passages formedby openings o and o. The air-shaft A is of such size and capacity,proportioned to the size of the stove, as to afford a safety-escape forthe excessive accumulation of gases. The advantage of this arrangementas embodied in my device is as follows: The magazine affords the usualautomatic feed, and when the register R is closed the air-shaft alwaysaffords a safety-exit for the accumulated coalgas from thecombustion-chamber below the partition. This arrangement obviates thedanger usually7 incident to the escape of coalgas and is a safeguardagainst carelessness in operating the register-plate R-a constant menaceto the occupants of rooms heated by stoves. When the register is closed,the ascending or direct upward draft from the fire is cut off, and thedraft is thereupon converted into an oblique or horizontal draft fromthe surface of the re to the lower end of the air-shaft A and the lowestpossible support given to the continued combustion upon the grate Gconsistent with safety to the occupants of the room heated by the stove;or, in other words, when the register is closed the least possibleamount of fuel is consumed upon the grate Gr consistent with the safetyof the occupants of the room heated by the stove. The said oblique draftby diverting the heat from about the magazine greatly reduces thedifficulty arising fr0`m the ignition and consumption of the fuel withinthe magazine. Economy and prudence are thus happily combined.

Having thus explained the mode of construction and the nature and objectof my invention, what I claim as novel, and for which I seeklLettersPatent, is the following, to Wit:

In a stove, the combination with the casing, of a combined register andcross-partition above the grate, means for opening and closing saidregister, a fuel-magazine depending from said cross-partition, a coverupon the upper end or mouth of said magazine and adapted to admit fueland to prevent draft through the same, a door in the casing above saidcross-partition and communicating with the mouth of said magazine andadapted to admit fuel. a door in thercasing below said cross-partitionand adapted for regulating the fire, anda safety-shaft extendingdownward from said cross-partition and near said casing and adapted toinduce an oblique draft of the gases arising from thefcombustion of fueland thereby to moderate the combustion of fuel upon the grate and toretard the ignition of fuel within the magazine, substantially asdescribed.
